High visibility first-order subwavelength interference based on light pulse storage via electromagnetically induced transparency

Abstract We achieved high visibility first-order subwavelength interference based on light pulse storage and retrieval technique via electromagnetically induced transparency (EIT) effect in a Pr3+:Y2SiO5 crystal. The interference field distribution of a double-slit was first stored in a Pr3+:Y2SiO5...
